A new study from The Auk: Ornithological Advances explores how male juncos adjust their courtship behavior to their social landscape, finding that while both paired and unpaired males will try to get the attention of a new female on their turf, they go about it in different ways.https://phys.org/news/2017-05-male-birds-adjust-courtship-behavior.html

Plants & Animals Wed, 03 May 2017 14:00:03 EDTnews413032027Courtship behavior trapped in 100-million-year-old amberCourtship behaviours, frequent among modern insects, have left extremely rare fossil traces. In odonates, the male must persuade the female to mate in tandem and the female should be willing to engage her genitalia with the male's. Many territorial odonatans display their courtship by high-frequency wing-beats towards an approaching female. Most courtship, mating and parenting (social-sexual) behaviour cannot be preserved, and fossil reports are therefore few and ambiguous. No courtship behaviors were previously recorded for fossil odonatans.https://phys.org/news/2017-03-courtship-behavior-million-year-old-amber.html

Literally. A new study by UCSB evolutionary biologists Todd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of species—thereby impacting global diversity.

Research published Feb. 3, 2016 in Neuron now demonstrates that the male fruit fly also displays this complex behavior during courtship, adjusting the amplitude of his song depending on how far away he is from a female. Studying this process in the fruit fly can help shed light on the building blocks for social interactions across the animal kingdom.https://phys.org/news/2016-02-fruit-flies-adjust-courtship-song.html

Whenever species evolve to feed at different depths, their courtship evolves as well. In the shallows where the light is good, males build sand castles to attract females. Males of deep-dwelling species dig less elaborate pits and compensate with longer swimming displays.

A dominant male attracts choice females to his territory by dancing seductively. If the female is sufficiently impressed, she lays her eggs and immediately collects them in her mouth, where the male fertilizes them. And, in some species, every once in a while, a lower-ranking male will dart into the scene and try to fertilize a few eggs before the dominant male knows what's happened.https://phys.org/news/2012-06-african-cichlid-noisy-courtship-ritual.html
